I have a cast model that is merged to created a machined model. In the machined drawing I want to show a dimension from the cast model. In WF4 you could show/erase and select features from the cast model. Now in WF5 I try to show anotations/Dimension and it'll allow me to select the merged feature, but not any features that are part of the cast part. How can I get the cast dimensions I want to show up in the machined print???
